Subject: i965/nir: Enable NIR lowering of txf and rect offsets
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9f32721f8695f3e55849dce015da3b53d1af5d57;p=mesa.git

i965/nir: Enable NIR lowering of txf and rect offsets

This fixes the following piglit tests on gen6+:

tex-miplevel-selection textureProjGradOffset 2DRect
tex-miplevel-selection textureGradOffset 2DRect
tex-miplevel-selection textureGradOffset 2DRectShadow
tex-miplevel-selection textureProjGradOffset 2DRect_ProjVec4
tex-miplevel-selection textureProjGradOffset 2DRectShadow
